The children had great fun creating structures using spaghetti and marshmallows. The challenge was to build a strong and tall tower that could take the weight of a number of cups, using just these two materials. The different groups discovered, through trial and error, that triangles were strong shapes for this task. By combining many triangles together some groups made very strong towers that held many cups! I think the most enjoyable part of the project was eating the marshmallows at the end though!
